Requesting VLF dump data
To obtain dump data for a VLF class, you need to dump both the
VLF address space and its associated data spaces. First, use the DISPLAY
command to determine the data spaces assigned to the VLF job:
D J,VLF
Then, use the DUMP command to dump the data, replacing clsname with
the name of a VLF class:
DUMP COMM=(DUMP OF VLF)
The system issues message IEE094D to prompt the operator for information.
Enter the following replies:
R xx,JOBNAME=VLF,CONT
R yy,DSPNAME=('VLF'.Dclsname,'VLF'.Cclsname),END
See z/OS MVS System Commands for more information about the DISPLAY and DUMP commands.
